Load an image then save a new one will increase the file size?

Reproducible Code

#include "tgafunc.h"

int main(){
    uint8_t* data;
    tga_info* info;
    tga_load(&data, &info, "./assets/cut_fish/base_color.tga");

    tga_save_from_info(data, info, "./output.tga");

    tga_free_data(data);
    tga_free_info(info);
    return 0;
}

The original file "base_color.tga" is 8.64MB, and the output.tga is 12MB.

Why is that?

This may cause the image that foolrenderer produces much bigger than it should be.

Because tgafunc currently does not support RLE compression, image data is stored in raw, so the file becomes larger. I will add RLE in the future.
